Learn how highway asphalt pavement construction uses milling and paving to restore surface profile, improve overlay preparation, and support material recycling in road rehabilitation.

In highway asphalt pavement construction, milling and paving are often used together to restore worn surfaces, correct profile issues, and prepare the roadway for a new overlay. Pavement milling, also called cold planing or asphalt milling, can remove only the thickness needed for leveling and smoothing or extend to full-depth removal, depending on project requirements. This method is commonly chosen because it can address rutting, raveling, bleeding, uneven ride quality, and grade-related drainage issues before new asphalt is placed.
